Because the backlight is integral to the screen on this model, fixing it requires replacing the screen. This may cost more than the purchase price of a new machine. We'll see.
In the meantime I'm looking around for an HDMI monitor cable so I can plug the Chromebook into an old monitor I have hanging around.
Online communication to and from me will be spotty until I get this problem dealt with. Text me or call if you want to get in touch.
